Why DMARC is neccasary
DMARC stands for Domain based
Messege Authentication, Reporting and Conformance.
DMARC is a set of
protocols that are used to authenticate the email senders domain. It provides
the information to the ISPs about the senders domain. It helps in identifying
whether the sender is trying to send spoofing mails in your inbox .
DMARC is able to identify a mail by using
two different protocols i.e. SPF (Sender Policy Framework) and DKIM (Domain
Keys Identified Mail). For a domain to get a "PASS" from DMARC it
firstly should get a "PASS" from the SPF and DKIM.
DMARC is a record and is stored &
updated in TXT record of the DNS .
DMARC offers three types of policy settings
for the emails:
1. None policy:
In this policy, no actions are taken
against any type of spoofing mails, only reports are generated and provided to
get the updates.
2. Quarantine Policy:
In this policy, the spoofing mails are
filtered and sent to the junk folder or spam folder.
3. Reject Policy
In this policy,the spoofing mails are bounce back to the senders
domain, if they do not "PASS" the DMARC protocols.
